I have used this for TC amplification with good results,

has built in CJC, as long as you keep the TC termination as close to the IC pins you're golden.
thanks for the response,
my real problem is I have no time to prototype this, but need a well designed text description. I really hate engineering this way but sometimes thats how it goes. I certainly know things never work as well at the bench as on paper.
Im getting from your response that...
I am trying to spec a project, general theory of operation:
have 4 fluids: air(sterile), and 3 aqueous solutions
use the air to flush a (semi) ufluidics card between reagents
the first two reagents are ~mL washes through the entire card (Q=1200uL/min <or less is ok> ), spec grav~ 1.1 , 0.9 -...
